A lfourth important object of the invention is to provide a novel suction hood arrangement as hereinafter set forth, wherein the hood, adapted "to be associated with the comb of a warping mafchine andwith the idler roll over which threads moving `through the comb pass after leaving said comb, the hood having intake ports associated with said comb and roll. A fifth important object of the inventionis to provide a novel suction hood for a textile 'warping `machine as hereinafter set forth, wherein the 1hood has Van intake opening extending over the "surface "of the thread massed on the beam and maintaining constant distance from said thread surface.

NA sixth important `object of the invention is 'to -provide a suction hood for a warping machine, as hereinafter set forth, wherein the' hood is `mounted in a novel manner to swing about the `axis on which the beam swings whereby to mainltain constant spatial relation to saidbeam., A seventh important object of the invention is to` provide for such a hood, as hereinafter described,` a suction pipe connected thereto and Vswiveledto swing `of the beam. Y

An eighth important object of the `vinvention is with the hood about the axis i to provide for the comb of a warping machine, as

hereinafter described, a suction hood so mounted and arranged that it may be readily swung into and out of operative relation to saidcomb.

A `ninth important object of the invention is to provide a suction hood for a comb, as hereinafter described, so associated with the stop motion of the machine that the hood will be raised `,clear of the comb upon operation of such stop motion.

With the above and other objects in View, as will be presently understood, the invention consists in general of certain novel details of con- 5 struction and combinations of parts hereinafter fully described, illustrated in the accompanying drawings and particularly pointed out in the appended claims.

In the accompanying drawings, like characters 10 of reference indicate like'parts in the several views, and;

Figure l is a front elevation of a warper showing the invention applied thereto,

Ii-Jl of Figure 1, and

Figure 5 is a fragmentary section on the line l 5-"5 of Figure 1.

The machine here illustrated is to be understood as merely typical of warpers and much of the detail is omitted as being unnecessary to an 25 understanding of the invention and as tending to obscure the latter. As here shown the warper `includesja pair of parallel side frame members Hland il; Swinging arms l2 and i3 are pivoted to the respect-,ivel frames l0 and il to swing vabout 3 0 a 'common axis A-A (Figure 3). At the free t" ends of these arms are provided bearings l for the pintles i5 of a warp beamV I The warp `beam is thus mounted so that it may swing vertically about the axis A-A. In many warpers 3 5 an idler `roll revolving on a fixed axis is provided "f" `beneath the warp beam on which the latter rests so that, as the warp .is wound thereon and the jdiameterof the warp mass increases the beam rises. This construction is not deemed necestf1@ sary to show in the present disclosure. A At eachV side `of the warper is a frame i'i each consisting 'of a bearing member i8 from which extends forwardly a pairl of diverging armsv i9 and 20. The `free ends of the arms i9 are con- 45 nected by a cross-bar 2| and theparms 2i] are connected by a cross-bar 22. The arms i9 and of eachmember Il carry yokes 23. Fixed in -fthe yokes 23 is a suction hood 2131 extending across l 21 from which extends rearwardly a suction pipe 28 having an outturned elbow 29 which connects With a swivel pipe joint 30. Each of the swivel joints 30 has a downwardly extending elbow 3l connected thereto and Aextending from these elbows are pipe lengths 32 bent inwardly at their rear ends to form elbows 33 which are connected by a cross-pipe 34. At 35 is a suction fan to the intake 36 of which is connected a T branch 31 leading from the pipe 34. It is particularly to be noted that the axes of the joints 30 coincide with the axis A-A so that the hood 24 may rise and fall with the beam I6 while maintaining a constant positional relation with said beam. The fan 35 may have its output end connected to any desired place by a pipe line such as 35a, and a suitable filter may be provided to receive air and entrained material from the fan as clearly shown in my prior Patent No. 2,057,139 of Octo ber 13, 1936.

On the upper ends of the side frames I0 and Il is mounted a transverse bar 38 provided with the usual guide comb teeth 39. Bearings 40 are provided forwardly of the bar 33 and these bearings receive the journals 4| of an idler roll 42. The yarn or warp threads T run from yarn cheeses 43 on a creel 44 (Figure 2) tothe comb and thence over the idler roll 42 and down to the beam. Only a few of these warp threads are here shown but it is, of course, well understood that the beam is filled from end to end.

A suction pipe 45 leads from a suitable fan (not shown) and extends upwardly between the creel and warper. This pipe has a lateral elbow 46 at its upper end and this elbow is connected to a swivel pipe joint 41 having a horizontal axis of revolution parallel to the axis A-VA. Connected to this swivel joint is a pipe elbow 48 from which the pipe extends forwardly as at 49. The forward end of the pipe 49 is 'branched to provide ay pair of Y branch arms 59. The forward ends of the arms 50 are connected to flaring casings 5I from the forward ends of which extend hood sections 52 arranged side by side in spaced relation. Each of these hood sections is provided with semi-lunate sides 53 extending normally forward over the comb Vand downwardly in front of the idler roll 42. The upper and forward edges of these sides are convex as at 54 and the lower and rear edges of said sides are concave as at 55 and the edges 54 and 55 merge at their forward ends into a semi-circular edge 56. Supported by these sides is a wrapper sheet 51 of Celluloid or other suitable transparent material which follows the contour of the edges of the sides 53. Adjacent the edges 56 between the edges 54 this wrapper sheet 51 is provided with an intake slot 58 which thus confronts the idler roll 42. The under side of the wrapper sheet above the comb is provided with an intake slot 59 and from the front and rear edges of the slot extend downwardly converging lips between which the upper ends of the teeth 39 are received when the hood is in active position. It will now be plain that the hoods 52 may swing up and down about the axis of the joint 41.V

In order that the operator may easily handle the hoods 52 to raise them and obtain access to the comb, each of the branches 5I] is provided with a collar 6I to which is connected the lower end of a cable or Wire 62.`VV These members 62 unite with a single cable or wire 63 which leads upwardly and passes over a pulley supported in a hanger 64- attached to the ceiling 65. The end portion 66 of the cable 63 depends from the pulley 64 and carries a counterweight 61 of suicient mass to counterbalancesubstantially all of the effective weight of the hoods 52 and the parts connecting them with the swivel joint 41. By these means the operator need exert but slight lifting effort to raise the hoods.

It is desirable that the hoods 52 be lifted whenever it happens that the electric creel stop motion (not shown) operates to stop the winding of yarn on the beam. To this end the pipe 49 is provided with a collar 68 adjacent the joint 41 and to this collar is connected a link or rod 69 which is in turn connected to a lift mechanism 10 operative upon operation of the stop motion of the machine to which this invention is applied. As here shown the mechanism 10 includes a solenoid core 1I the upper part of which is surrounded by a solenoid winding 12 supported by a bracket 13 carried by the ceiling 65. Wires 14 connect the solenoid winding 12 with the stop motion circuit of the machine so that whenever this circuit is energized the solenoid will also be energized and draw up the core 1I and thus lift the hoods, but little power being required for this because of the counterweight arrangement above described.

In the oper-ation of this device the suction produced by the fan or fans causes a very considerable draft to flow into the hood or hoods through the slot therein. The consequence is that any floating lint or the like is entrained in the air stream ilowing into the hood and carried away from those points at which it tends to deposit on the machine and be picked up by the moving yarn or threads. Also, if for any reason there has been a deposit of lint, dust or the like at these points as soon' as the suction is produced to set up the air currents above mentioned the deposited material will be caught by these currents and drawn into the hood and thus conveyed away from the points of deposit. For instance, if the threads or yarn has picked up any dust or lint in passing to the hoods it will be removed as it passes thereunder to the hood. By having the wrapper sheet transparent the operator is enabled to observe at all times the condition of the warp threads as they pass through the comb. Thus, even without any connection to a stop motion, the operator can note if a thread breaks so that he may stop the machine and make any 55'0 necessary connections for broken threads. The manner in which the hood is suspended over the comb enables this to be done very readily since the operator may raise the hood from its normal position and thus obtain ready access to the comb. This lifting of the hood also enables the yarn or thread to be properly positioned in the comb in preparing the warper or other machinery for operation. The control of the hood position by the stop motion device relieves the operator from the necessity of lifting the hood when a break occurs.

While the hoods herein described have been set forth as associated particularly with a warper beam and the comb of a warper mechanism yet it is to be understood that these hoods may be used with other forms of textile machinery. For instance, it is common in continuous dyeing operations to use one or more guide combs in connection with the dyeing machine and such a hood as has been above described could be advantageously used in connection with these guiding combs.
